Avoid public transportation when possible, limit nonessential travel, work from home and skip social gatherings. Don’t go to crowded restaurants or busy gyms. You can go outside, as long as you avoid being in close contact with people.

If you develop a high fever, shortness of breath or another, more serious symptom, call your doctor. (Testing for coronavirus is still inconsistent — there are not enough kits, and it’s dangerous to go into a doctor’s office and risk infecting others.) Then, check the Centers for Disease Control and Prevention website and your local health department for advice about how and where to be tested.

Wash your hands, wash your hands, wash your hands. That splash-under-water flick won’t cut it anymore.

Also, clean “high-touch” surfaces, like phones, tablets and handles. Apple recommends using 70 percent isopropyl alcohol, wiping gently. “Don’t use bleach,” the company said.

To disinfect any surface, the C.D.C. recommends wearing disposable gloves and washing hands thoroughly immediately after removing the gloves. Most household disinfectants registered by the Environmental Protection Agency will work.

There’s a lot of information flying around, and knowing what is going on will go a long way toward protecting your family.

Right now, there’s no reason for parents to worry, the experts say; coronavirus cases in children have been very rare. The flu vaccine is a must, as vaccinating children is good protection for older people. And take the same precautions you would during a normal flu season: Encourage frequent hand-washing, move away from people who appear sick and get the flu shot.

Unless you are already infected, face masks won’t helpFace masks have become a symbol of coronavirus, but stockpiling them might do more harm than good. First, they don’t do much to protect you. Most surgical masks are too loose to prevent inhalation of the virus. (Masks can help prevent the spread of a virus if you are infected. The most effective are the so-called N95 masks, which block 95 percent of very small particles.)Second, health care workers and those caring for sick people are on the front lines. Last month, the surgeon general urged the public to stop stockpiling masks, warning that it might limit the amount of resources available to doctors, nurses and emergency professionals.

No. The first testing in humans of an experimental vaccine began in mid-March. Such rapid development of a potential vaccine is unprecedented, but even if it is proved safe and effective, it probably will not be available for 12 to18 months.

If you’re sick and you think you’ve been exposed to the new coronavirus, the C.D.C. recommends that you call your healthcare provider and explain your symptoms and fears. They will decide if you need to be tested. Keep in mind that there’s a chance — because of a lack of testing kits or because you’re asymptomatic, for instance — you won’t be able to get tested.

That’s not a good idea. Even if you’re retired, having a balanced portfolio of stocks and bonds so that your money keeps up with inflation, or even grows, makes sense. But retirees may want to think about having enough cash set aside for a year’s worth of living expenses and big payments needed over the next five years.

But these latest shifts challenge key infection control assumptions that go back a century, putting a lot of what went wrong last year in context

They may also signal one of the most important advancements in public health during this pandemic.

If the importance of aerosol transmission had been accepted early, we would have been told from the beginning that it was much safer outdoors, where these small particles disperse more easily, as long as you avoid close, prolonged contact with others.

We would have tried to make sure indoor spaces were well ventilated, with air filtered as necessary.

Instead of blanket rules on gatherings, we would have targeted conditions that can produce superspreading events: people in poorly ventilated indoor spaces, especially if engaged over time in activities that increase aerosol production, like shouting and singing

We would have started using masks more quickly, and we would have paid more attention to their fit, too. And we would have been less obsessed with cleaning surfaces.

The implications of this were illustrated when I visited New York City in late April — my first trip there in more than a year.

A giant digital billboard greeted me at Times Square, with the message “Protecting yourself and others from Covid-19. Guidance from the World Health Organization.”

That billboard neglected the clearest epidemiological pattern of this pandemic: The vast majority of transmission has been indoors, sometimes beyond a range of three or even six feet. The superspreading events that play a major role in driving the pandemic occur overwhelmingly, if not exclusively, indoors.

The billboard had not a word about ventilation, nothing about opening windows or moving activities outdoors, where transmission has been rare and usually only during prolonged and close contact. (Ireland recently reported 0.1 percent of Covid-19 cases were traced to outdoor transmission.)

Mary-Louise McLaws, an epidemiologist at the University of New South Wales in Sydney, Australia, and a member of the W.H.O. committees that craft infection prevention and control guidance, wanted all this examined but knew the stakes made it harder to overcome the resistance. She told The Times last year, “If we started revisiting airflow, we would have to be prepared to change a lot of what we do.” She said it was a very good idea, but she added, “It will cause an enormous shudder through the infection control society.”

In contrast, if the aerosols had been considered a major form of transmission, in addition to distancing and masks, advice would have centered on ventilation and airflow, as well as time spent indoors. Small particles can accumulate in enclosed spaces, since they can remain suspended in the air and travel along air currents. This means that indoors, three or even six feet, while helpful, is not completely protective, especially over time.

To see this misunderstanding in action, look at what’s still happening throughout the world. In India, where hospitals have run out of supplemental oxygen and people are dying in the streets, money is being spent on fleets of drones to spray anti-coronavirus disinfectant in outdoor spaces. Parks, beaches and outdoor areas keep getting closed around the world. This year and last, organizers canceled outdoor events for the National Cherry Blossom Festival in Washington, D.C. Cambodian customs officials advised spraying disinfectant outside vehicles imported from India. The examples are many.

Meanwhile, many countries allowed their indoor workplaces to open but with inadequate aerosol protections. There was no attention to ventilation, installing air filters as necessary or even opening windows when possible, more to having people just distancing three or six feet, sometimes not requiring masks beyond that distance, or spending money on hard plastic barriers, which may be useless at best

clear evidence doesn’t easily overturn tradition or overcome entrenched feelings and egos. John Snow, often credited as the first scientific epidemiologist, showed that a contaminated well was responsible for a 1854 London cholera epidemic by removing the suspected pump’s handle and documenting how the cases plummeted afterward. Many other scientists and officials wouldn’t believe him for 12 years, when the link to a water source showed up again and became harder to deny.

Along the way to modern public health shaped largely by the fight over germs, a theory of transmission promoted by the influential public health figure Charles Chapin took hold

Dr. Chapin asserted in the early 1900s that respiratory diseases were most likely spread at close range by people touching bodily fluids or ejecting respiratory droplets, and did not allow for the possibility that such close-range infection could occur by inhaling small floating particles others emitted

He was also concerned that belief in airborne transmission, which he associated with miasma theories, would make people feel helpless and drop their guard against contact transmission. This was a mistake that would haunt infection control for the next century and more.

It was in this context in early 2020 that the W.H.O. and the C.D.C. asserted that SARS-CoV-2 was transmitted primarily via these heavier, short-range droplets, and provided guidance accordingly

Amid the growing evidence, in July, hundreds of scientists signed an open letter urging the public health agencies, especially the W.H.O., to address airborne transmission of the coronavirus.

Last October, the C.D.C. published updated guidance acknowledging airborne transmission, but as a secondary route under some circumstances, until it acknowledged airborne transmission as crucial on Friday. And the W.H.O. kept inching forward in its public statements, most recently a week ago.

Linsey Marr, a professor of engineering at Virginia Tech who made important contributions to our understanding of airborne virus transmission before the pandemic, pointed to two key scientific errors — rooted in a lot of history — that explain the resistance, and also opened a fascinating sociological window into how science can get it wrong and why.

Dr. Marr said that if you inhale a particle from the air, it’s an aerosol.

biomechanically, she said, nasal transmission faces obstacles, since nostrils point downward and the physics of particles that large makes it difficult for them to move up the nose. And in lab measurements, people emit far more of the easier-to-inhale aerosols than the droplets, she said, and even the smallest particles can be virus laden, sometimes more so than the larger ones, seemingly because of how and where they are produced in the respiratory tract.

Second, she said, proximity is conducive to transmission of aerosols as well because aerosols are more concentrated near the person emitting them. In a twist of history, modern scientists have been acting like those who equated stinky air with disease, by equating close contact, a measure of distance, only with the larger droplets, a mechanism of transmission, without examination.

Since aerosols also infect at close range, measures to prevent droplet transmission — masks and distancing — can help dampen transmission for airborne diseases as well. However, this oversight led medical people to circularly assume that if such measures worked at all, droplets must have played a big role in their transmission.

Another dynamic we’ve seen is something that is not unheard-of in the history of science: setting a higher standard of proof for theories that challenge conventional wisdom than for those that support it.

Another key problem is that, understandably, we find it harder to walk things back. It is easier to keep adding exceptions and justifications to a belief than to admit that a challenger has a better explanation.

The ancients believed that all celestial objects revolved around the earth in circular orbits. When it became clear that the observed behavior of the celestial objects did not fit this assumption, those astronomers produced ever-more-complex charts by adding epicycles — intersecting arcs and circles — to fit the heavens to their beliefs.

In a contemporary example of this attitude, the initial public health report on the Mount Vernon choir case said that it may have been caused by people “sitting close to one another, sharing snacks and stacking chairs at the end of the practice,” even though almost 90 percent of the people there developed symptoms of Covid-19

So much of what we have done throughout the pandemic — the excessive hygiene theater and the failure to integrate ventilation and filters into our basic advice — has greatly hampered our response.

Some of it, like the way we underused or even shut down outdoor space, isn’t that different from the 19th-century Londoners who flushed the source of their foul air into the Thames and made the cholera epidemic worse.

Righting this ship cannot be a quiet process — updating a web page here, saying the right thing there. The proclamations that we now know are wrong were so persistent and so loud for so long.

the progress we’ve made might lead to an overhaul in our understanding of many other transmissible respiratory diseases that take a terrible toll around the world each year and could easily cause other pandemics.

So big proclamations require probably even bigger proclamations to correct, or the information void, unnecessary fears and misinformation will persist, damaging the W.H.O. now and in the future.

I’ve seen our paper used in India to try to reason through aerosol transmission and the necessary mitigations. I’ve heard of people in India closing their windows after hearing that the virus is airborne, likely because they were not being told how to respond

The W.H.O. needs to address these fears and concerns, treating it as a matter of profound change, so other public health agencies and governments, as well as ordinary people, can better adjust.

It needs to begin a campaign proportional to the importance of all this, announcing, “We’ve learned more, and here’s what’s changed, and here’s how we can make sure everyone understands how important this is.” That’s what credible leadership looks like. Otherwise, if a web page is updated in the forest without the requisite fanfare, how will it matter?

With shortages of everything from auto parts to generic medicines and production delays in things like iPhones and Diet Coke, a great deal of pain is coming from the closing of Chinese factories. That proliferating damage has central banks and financial analysts talking about a global recession in the coming months.

As a baseline, several factors work against the United States. China’s authoritarian government can quarantine entire cities or order people off the streets in a way that would be hard to imagine in America, presumably giving China an advantage in slowing the spread of the disease. In addition, a large share of American workers lack paid sick days and millions lack health care coverage, so people may be less likely to stay home or to get proper medical care. And 41 percent of China’s population lives outside urban areas, more than twice the share in the United States. Diseases generally spread faster in urban areas.

When people pull back from interacting with others because of their fear of disease, the things they stop doing will frequently affect much bigger industries in the United States.

People may stop attending American sporting events. There have even been calls for the N.C.A.A. to play its March Madness college basketball tournament without an audience. But sports is a huge business in the United States. People spend upward of 10 times as much on sporting events as they do in China.

Who wants to go to the dentist or the hospital during an outbreak if a visit isn’t necessary? Yet health spending is 17 percent of the U.S. economy — more than triple the proportion spent in China.

But over all, the United States is substantially more reliant on services than China is.

A major coronavirus epidemic in the United States might be like a big snowstorm that shuts down most economic activity and social interaction only until the snow is cleared away. But the coronavirus could be a “Snowmaggedon-style storm” that hits the whole country and lasts for months.

Dr. Krogan and his colleagues set about finding proteins in our cells that the coronavirus uses to grow. Normally, such a project might take two years. But the working group, which includes 22 laboratories, completed it in a few weeks.

In 2011, Dr. Krogan and his colleagues developed a way to find all the human proteins that viruses use to manipulate our cells — a “map,” as Dr. Krogan calls it. They created their first map for H.I.V.

That virus has 18 genes, each of which encodes a protein. The scientists eventually found that H.I.V. interacts, in one way or another, with 435 proteins in a human cell.

In February, the research group synthesized genes from the coronavirus and injected them into cells. They uncovered over 400 human proteins that the virus seems to rely on.

The flulike symptoms observed in infected people are the result of the coronavirus attacking cells in the respiratory tract.

The new map shows that the virus’s proteins travel throughout the human cell, engaging even with proteins that do not seem to have anything to do with making new viruses.

Kevan Shokat, a chemist at U.C.S.F., is poring through 20,000 drugs approved by the Food and Drug Administration for signs that they may interact with the proteins on the map created by Dr. Krogan’s lab.

If promising drugs are found, investigators plan to try them in an animal infected with the coronavirus — perhaps ferrets, because they’re known to get SARS, an illness closely related to Covid-19.

Even if some of these drugs are effective treatments, scientists will still need to make sure they are safe for treating Covid-19. It may turn out, for example, that the dose needed to clear the virus from the body might also lead to dangerous side effects.

In past studies on animals, remdesivir blocked a number of viruses. The drug works by preventing viruses from building new genes.

In February, a team of researchers found that remdesivir could eliminate the coronavirus from infected cells. Since then, five clinical trials have begun to see if the drug will be safe and effective against Covid-19 in people.

Other researchers have taken startling new approaches. On Saturday, Stanford University researchers reported using the gene-editing technology Crispr to destroy coronavirus genes in infected cells.

The UK is not alone. Many other nations were slow to respond to the threat at care home facilities, and the consequences have been devastating.

Comparing death tolls can be difficult: some countries have separate data covering elderly care homes, while others include facilities for those with disabilities. Some countries do not include in their data those residents who die in hospitals, some have regional variation​, and some have no data at all.

There had been 1,661 coronavirus deaths among care home residents out of 3,395 total coronavirus deaths in Sweden by May 14, or 49%, according to LTCcovid's report.

19 residents out of 110 had died in the past two months, but only five were confirmed Covid-19 deaths -- the rest were "undetermined," he said. He said he thought there had been "slight under-reporting" of deaths in the UK because of a lack of testing, and said the situation had been "harrowing."

Raffaele Antonelli Incalzi, head of the Italian geriatric society SIGG, said in a statement in early April that care homes were "biological time bombs," in part because overcrowded hospitals were moving elderly patients to unprepared homes.

Elderly care sector professionals and care home workers published a letter to Health Minister Olivier Véran on March 20 expressing alarm and requesting 500,000 masks per week in affected areas, to which he agreed.

By March 24, the Spanish army was drafted in to help and found "abandoned" ​care home residents dead in their beds, according to Defense Minister Margarita Robles. The government said at its briefing the next day that the information had been passed to the public prosecutor, who was investigating. New care home guidelines called for extended isolation measures, but some homes said they would now have to send all staff home to comply.

She said the DHSC was prioritizing testing in care homes and had provided £3.2 billion ($3.9 billion) to local authorities to ease pressure on services including care homes, as well as an additional £600 million ($730 million) for homes last week. "Since the start of this pandemic we have worked to ensure our care homes and frontline care workforce get the support they need. Almost two thirds of care homes have not had an outbreak and deaths in all settings, including care homes, are falling."

A similar story played out in France, where coronavirus fatalities among care home residents in all settings make up more than half of all coronavirus deaths recorded as of May 18, according to health ministry data used in the LTCcovid report.

The UK initially did not record care home deaths. While the latest official ONS data for England and Wales shows that 38% of coronavirus deaths occurred in care homes, LTCcovid said the figure could be far higher.

LTCcovid's report found that 3,890 of Canada's 4,740 coronavirus-linked deaths took place among care home residents as of May 8, or 82%, and Health Canada told CNN the percentage was nearly 80% on May 19. Canada's largest province, Ontario, has announced an independent inquiry.

Of the 247 total Covid-19 deaths in South Korea that had been confirmed as of April 30, 84 were care home residents -- a share of 34%. No large care home outbreaks have occurred since the measures were implemented.

Over a 13-week period, our study allowed us to capture people’s assessments of fresh news articles in real time. Each day of the study, we relied on a fixed, pre-registered process to select five popular articles published within the previous 24 hours

The five articles were balanced between conservative, liberal and non-partisan sources, as well as from mainstream news websites and from websites known to produce fake news. In total, we sent 150 total articles to 90 survey respondents each

We also sent these articles separately to six independent fact checkers, and treated their most common response — true, false/misleading, or cannot determine — for each article as the “correct’’ answer for that article.

When shown an article that was rated “true” by the professional fact checkers, respondents correctly identified the article as true 62 percent of the time. When the source of the true news story was a mainstream news source, respondents correctly identified the article as true 73 percent of the time.

However, for each article the professional fact checkers rated “false/misleading,” the study participants were as likely to say it was true as they were to say it was false or misleading. And roughly one-third of the time they told us they were unable to determine the veracity of the article. In other words, people on the whole were unable to correctly classify false or misleading news.

four of the articles in our study that fact checkers rated as false or misleading were related to the coronavirus.

All four articles promoted the unfounded rumor that the virus was intentionally developed in a laboratory. Although accidental releases of pathogens from labs have previously caused significant morbidity and mortality, in the current pandemic multiple pieces of evidence suggest this virus is of natural origin. There’s little evidence that the virus was manufactured or altered.

Only 30 percent of participants correctly classified them as false or misleading.

respondents seemed to have more trouble deciding what to think about false covid-19 stories, leading to a higher proportion of “could not determine” responses than we saw for the stories on other topics our professional fact checkers rated as “false/misleading.” This finding suggests that it may be particularly difficult to identify misinformation in newly emerging topics

Study participants with higher levels of education did better on identifying both fake news overall and coronavirus-related fake news — but were far from being able to correctly weed out misinformation all of the time

In fact, no group, regardless of education level, was able to correctly identify the stories that the professional fact checkers had labeled as false or misleading more than 40 percent of the time.

Taken together, our findings suggest that there is widespread potential for vulnerability to misinformation when it first appears online. This is especially worrying during the current pandemic

In the current environment, misinformation has the potential to undermine social distancing efforts, to lead people to hoard supplies, or to promote the adoption of potentially dangerous fake cures.

our findings suggest that non-trivial numbers of people will believe false information to be true when they first encounter it. And it suggests that efforts to remove coronavirus-related misinformation will need to be swift — and implemented early in an article’s life-cycle — to stop the spread of something else that’s dangerous: misinformation.

Meanwhile, 2019-nCoV, which causes symptoms similar to the flu, has killed about 2% of the 31,500 people it has infected so far, but has spread to more than 20 countries—including, crucially (at least in terms of understanding media coverage), the U.S. Any time an issue affects the U.S., the Western press kicks into high gear, Miller says.

After the 2014-2016 Ebola outbreak, the U.S. press was criticized for overstating the possible threat to Americans.

There is a key difference between coronavirus and climate crisis, of course, and it is shame. “We didn’t know coronavirus was coming,” says Stirling. “We’ve known the climate crisis was on the cards for 30 or 40 years.” And yet – despite being inadequately prepared because of an underfunded, under-resourced NHS – the government can swiftly announce an emergency pandemic plan.

The tumult in the U.S. economy still pales in comparison to the damage being felt in other countries. In China, auto sales cratered 80% last month, while a plunge in tourism is expected to push Italy and perhaps France into a recession.

The U.S. Travel Association predicts that international travel to the United States will fall by 6% over the next three months. "There is a lot of uncertainty around coronavirus, and it is pretty clear that it is having an effect on travel demand — not just from China, and not just internationally, but for domestic business and leisure travel as well," the association's president, Roger Dow, said in a statement.

The final price of any vaccine should be one that governments of poor and rich countries alike can afford so all citizens can get it free at the point of care.

Without price controls, poor countries are unlikely to be able to afford or access enough vaccines to protect their populations.

A sad truth we have learned from past global pandemics is that poor people are hit first and worst. Vaccines are most urgently needed where health systems are fragile, and where the effects of this new coronavirus could be catastrophic.

Many countries lack the resources, infrastructure, and health care personnel to mount full-scale efforts to detect the virus and prevent it from spreading, meaning it will move quickly and easily among populations. In these settings, the number of cases is likely to grow exponentially, putting stress on already burdened health care workers and facilities and making it harder to provide timely care for those who are ill. Vaccines will be an important tool for preventing such a catastrophe.

For those with resources — rich countries and rich people — a vaccine would be valuable, one of several tools we will need to prevent the most serious effects of the new coronavirus. But for those who are poor or who live in poor countries, it may be essential. Without it, they will suffer disproportionately and unnecessarily.

To let a coronavirus vaccine be monopolized by the rich will perpetuate the unjust economics of outbreaks, where the poor always pay the heaviest price. Allowing this to happen would be a moral disgrace.

"In these kinds of public health emergencies, we need to be able to trust our leaders, be it public health, scientific or political leaders," Omer said. This will become particularly important in the coronavirus outbreak if there comes a time when the government needs to recommend major lifestyle adjustments to curtail the spread of the disease.

More than 136 million Americans voted in 2016, and a record number of them cast early ballots. But nearly 60% of voters still showed up on Election Day, waited in long lines, used communal pens and touched the same voting machines -- all dangerous moves in the coronavirus era.

"the investigation itself appears to be inconsistent" with its mandate.

As countries around the world struggle with new infection surges and outbreaks, China appears to be rebounding.

"more and more research suggests that the pandemic was likely to have been caused by separate outbreaks in multiple places in the world."

“Big parts of our brains are devoted to making sense of touch and our skin has billions of cells that process information about it,”

“The right type of friendly touch—like hugging your partner or linking arms with a dear friend—calms your stress response down. [Positive] touch activates a big bundle of nerves in your body that improves your immune system, regulates digestion and helps you sleep well. It also activates parts of your brain that help you empathize.”

Psychologist Sheldon Cohen and other researchers at Carnegie Mellon University cited hugging specifically as a form of touch that can strengthen the immune system in a 2014 study investigating whether receiving hugs—and more broadly, social support that gives the perception that one is cared for—could make people less susceptible to one of the viruses that causes the common cold.

Broadly speaking, the participants who had reported having more social support were less likely to get sick—and those who got more hugs were far more likely to report feeling socially supported.

Everybody should be open to people being a little more socially distant and not touching as much. Some of it will return and some of it won’t.”

Although there’s no exact substitute for human touch, if you’re struggling with this aspect of self-isolating in particular, there are a few alternatives that can offer similar health benefits for people who are social distancing

“When we’re touched [in a positive way], a cascade of events happens in the brain and one of the important ones is the release of a neurochemical called oxytocin,”

Keltner adds that dancing, singing or doing yoga with others via an online platform can also be highly effective substitutes for physical contact

“Not only would it be good to prevent coronavirus disease; it probably would decrease instances of influenza dramatically in this country,”

Zak says U.S. customs like shaking hands and hugging may be changed forever and suggests that non-tactile greetings like a nod, bow or wave may come to replace them. However, he says it will still be important to find ways to reintroduce the humanity of positive touch into in-person interactions without putting anyone’s physical or mental health in jeopardy.

“In-person interactions have a big effect on the brain releasing oxytocin, but interacting via video is actually not that [different],” he explains. “It’s maybe 80% as effective. Video conferencing is a great way to see and be seen.”

But for those who are quarantining alone or with people with whom they don’t have physical contact, loneliness and social isolation are growing health concerns.

this process reduces stress and improves immunity. “That’s super valuable in a time of pandemic.”

If you’re using a video chat service for work or school, Zak recommends that you take five minutes at the beginning of the call to focus on interpersonal connection.

to illustrate how dance parties like Daybreaker can be beneficial for people’s physical and mental health. “When you create a dance experience driven by music, community and participation, that’s how you’re able to release all four happy brain chemicals,” Agrawal says.

"For as long as we have citizens willing to follow their example, to carry on their burden, to continue their legacy, then America's cause will never fail and American freedom will never, ever die."

But that doesn't mean it isn't jarring, as the most wrenching moment so far approaches in the nation's battle against a pandemic that while ebbing in terms of total deaths is trending up in 18 states, is steady in 22 and easing in 10 more. More than 98,000 people in the US have now died from the coronavirus and more than 1.6 million have been infected. More than 30 million Americans have lost their jobs and the unemployment rate is approaching Great Depression levels.

There was little evidence of a deeper meaning to his presidency at this stage than personal and political grievances.

No White House could have been fully prepared for the disaster and subsequent economic hollowing of this year's pandemic

Trump spent much of Memorial Day, fulminating against Cooper, complaining that the North Carolina governor was "unable to guarantee" the arena for the convention in August can be filled to capacity. The President is determined to deploy the full pageantry of convention season to portray a nation and economy in the full throes of what he calls a "transition to greatness."

Yet such a spectacle as the Republican convention seems utterly incongruous with real-world events. Sports teams that use such arenas are expecting to play without fans for at least months in a bio-secure environment. The prospect of thousands of delegates pouring into convention cities from all over the country, including coronavirus hotspots, is a huge headache for organizers.

"In other words, we would be spending millions of dollars building the Arena to a very high standard without even knowing if the Democrat Governor would allow the Republican Party to fully occupy the space."

It was not immediately clear whether Trump and the Republican National Committee are serious about pulling the convention from Charlotte.

Trump has used federal resources multiple times to fly to his resorts and golf courses. Trump's two rounds this weekend struck critics as inappropriate during a national crisis and on a weekend when American remembers its war dead.

"Nearly 100,000 lives have been lost, and tens of millions are out of work. Meanwhile, the president spent his day golfing," Biden wrote in a tweet accompanying an online ad Saturday.

Trump may not come under such criticism had he not been so dismissive of Obama's afternoons on the golf course -- and saying he wouldn't have time to play golf if he was elected president.

On both sides of the Capitol, lawmakers, aides, police officers and reporters who had fled to secure locations have been warned that they might have been exposed to the coronavirus while hiding from the mob

“It angers me when they refuse to adhere to the directions about keeping their masks on,” Ms. Watson Coleman, a lung cancer survivor who will turn 76 next month, said in an interview. “It comes off to me as arrogance and defiance. And you can be both, but not at the expense of someone else.”

The scene that unfolded on Wednesday in that one secure room — where an offer of masks from Representative Lisa Blunt Rochester, Democrat of Delaware, was rejected by a group of Republicans — is emblematic of the challenge that has dogged Capitol Hill’s disorderly response to the pandemic.

Republicans accused Democrats, who needed their narrow majority fully present in person to confirm Ms. Pelosi as speaker, of subverting their own rules on the first day of the Congress

permitting the construction of a small plexiglass enclosure with its own ventilation system in one of the galleries so that lawmakers in a protective quarantine could vote in person

Complicating matters further, lawmakers in both parties have delayed receiving a vaccination, despite being granted primary access, arguing that essential workers needed to receive it first.
